BUTTON
BIT
Thread
drill bits are made by high quality alloy steel bar and
tungsten carbide inserts. Through heat treatment, our drilling
tools are tough enough to meet rock drilling demands and have the
least loss of energy while drilling the rocks. They serve in
railway, subway, highway, tunnel, mining, metallurgical
engineering, water conservancy...
worldwide.
Specifications
Diameter:
38--127mm
Thread: R25, R28, R32, R38, T38, T45, T51, ST58,
T60
Body:
Normal, Lengthen, Retrac
Drop
center / Standard skirt
Perfect in abrasive formations where there is
accelerated wear or in medium to hard rock when ballistic
s have tendency to break.
Drop
center / Retrac skirt
To be
used in medium-hard and fissured rock formations, better hole
deviation control.
Flat
front / Standard skirt
Ideal
for medium hard rock when the rock formation causes heavy gauge
wear on the bit, can also be used in very hard and abrasive rock
formations.
Flat
front / Retrac skirt
To be
used in the same applications as flat front / sphericals /
stanarf skirt when you create holes.
We can
design customized thread drill bits according to different
drilling application, and custom drill bits are applicable to drill
soft rock, loose-medium rock and hard
rock, we also supply Cross bits, Chisel bits, DTH
bits.

|
Domed/round
: domed/round s are usually used as
gauge s of DTH bits. Suitable for very abrasive and
very hard formations. |
|
| Parabolic/semi-ballistic: s parabolic s are usually used as gauge s and front s of DTH bits, suitable for medium abrasive and hard formations | |
|
Ballistic
: ballistic
are usually used as front s of DTH bits,
suitable for medium abrasive and medium hard
formations. they can also be used as
gauge s if the rock is soft
. |
|
|
Sharp
: sharp
s are usually used as front s of DTH bits for
softformations where fast penetration rates are
possible |
|
| Face Shape Selection | |
|
Concave
Face The all-round application bit face specifically for medium hard and homo generous rock formations good hole deviation control and good flushing capacity. |
|
|
Convex
Face This shape is suitable drill F8-13level(soft-medium-hard)rock drill steel body is not easy to wear .characterized by lower tooth bearing and wear is not serious,fast drilling speed ,but hole deviation. |
|
|
Double Gauge
Face This kind face shape is suitable for fast penetration rates in medium to hard rock formations .Designed for high air pressure and good resistance to steel wash step gauge bit . |
|
|
Flat
Face This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressure .Good penetration rates an resistance to steel wash. |
|
|
DROP
CENTER For high penetration rates in soft to medium hard and fissured rock formations low to medium air pressures. Maximum hole deviation control. |
